If you have Venomhide Ravasaur on a horde character, it gets converted to the Winterspring Frostsaber when you play an alliance character.

Yes, I suspected this as well. I play my ally toons all the time, and yesterday I logged onto a druid I hardly ever use that has the Venomhide Raptor. It's not the first time I log him though, but perhaps for a few weeks, so the change has to be quite recent?
Anyway, thanks for clearing up.

A lot of horde only mounts got made to transfer to alliance recently and vice versa. Though IDK how many, what I would like to see is this go into place for the tourny mounts, I certiantly don't want to lose them when I change.

For instance, I have 60 mounts on an alliance char and 120 on my horde. No idea why this is. If i have a sunreaver, I should have the silver covenant equivalent.

It was never Hardcore Vs Casual. It was Socialites Vs. Solo players

I have quite a few mounts that got converted with 5.1. Spectral Wolf -> Horse, all of my Horde mammoths (glad I didn't end up buying the Tundra one on Alliance), Spectral Wyvern -> Gryphon, Venomhide Ravasaur -> Frostsaber, Sunreaver Dragonhawk -> Silver Covenant Hippogryph (this is the only Tournament mount I have that got converted. I don't have the Sunreaver ground mount though, no idea if it does).

Sad that the Black War PVP mounts and other Tournament mounts didn't make it.
